Short-fused star Cowboys receiver Dez Bryant went on a 10-minute, profanity-filled rant at a reporter in the locker room Thursday, flipped out again after the tirade was mentioned on Twitter, and later wrote he was upset because he objected to a reporter’s use of racial slurs.

“Until they stop disrespecting this team I don’t give a f–k. Motherf–king sick!” Bryant raged, according to MMQB.com, and called all the reporters in the locker room “dirty” several times before he was led out by veteran tight end Jason Witten and coach Jason Garrett.

Bryant initially was upset about something a reporter had written, and had been asking for days where he was.

The 27-year-old later wrote on Twitter: “Yea I blew up on the media but report why I blew up on y’all…. Saying I don’t give a f–k about me and calling players n—-s is not professional…”

MMQB reported those accusations by Bryant about the reporter were “uncorroborated by any other teammates or media present.”

It’s the second time in two weeks Bryant has angrily lashed out at reporters. He went ballistic after the Nov. 1 game against the Seahawks when a reporter on Twitter suggested Bryant had taunted an injured Seattle player.

“I won’t ever, ever, ever wish bad on a player that’s been knocked down. C’mon, man. Stop with the bulls–t,” Bryant exclaimed. “Not once did I say, ‘That’s what you get.’ I got on one knee and prayed for the man.

“Y’all took that s–t too far. Whoever wrote that, whoever done that is a dirty motherf—-r,” Bryant said. “That really pissed me off. That ain’t right. That is not right. That is not right. That is not right.”

The Cowboys have lost six straight games, and Bryant has been limited to 12 catches and one touchdown during an injury-plagued season.
